Screw Pump · Pumps
Ensuring reliable operation and minimizing downtime is crucial for maintaining the efficiency of marine equipment. IMO AB’s ACG is designed to handle fuel oil and lube oil in an engine-room oil service setting. This marine-rated pump features a robust three-screw pump design driven by an electric motor. However, several common issues can affect its performance, such as screw wear caused by abrasive particles, mechanical seal leakage, and bearing damage from dry running or cavitation, which can lead to low pressure issues due to relief valve malfunctions. To keep the ACG running smoothly, it is essential to avoid dry running and maintain proper suction head and clean strainers. Regular inspection of screws and bearings during scheduled overhauls is also recommended. Spare parts such as a seal kit, bearing kit, gasket kit, and relief valve parts are readily available, along with a screw set, to facilitate quick and effective repairs when necessary.
